Bounding and unbounding higher extensions for SL2

We analyse the recursive formula found for various Ext groups for SL2(k), k a field of characteristic p , and derive various generating functions for these groups. We use this to show that the growth rate for the cohomology of SL2(k) is at least exponential. In particular, max{dimExtSL2(k)i (k,Δ(a))...
